WELL-CASING MACHINE.

Specification of Letters Patent.

Patented Oct. 1,1912.

To all whom it may concern:

Be it known that I, EDWARD J. PENNY- PAOKER, a citizen of the UnitedStates, residing at Los Angeles, in the county of Les Angeles and Stateof California, have 111- vented a new and useful Well-Casing Machine, ofwhich the following is a specification.

This invention relates to a machine for manufacturing sections ofwell-casing by telescoping and riveting together joints of sheet-metalpipe. In manufacturing wellcasing of this description separate singlejoints of pipe are first made from metal sheets the edges of which areriveted or welded together with a longitudinal seam; then the ends ofsuch joints are squared, and then the end of one joint which is slightlytapered for the purpose, is forced into another joint to which it istightly fitted, and other joints are successively telescoped therewithuntil the required pipesection which may be of any desired length,

TI is formed. It is desirable that the pipejoints thus united shall fiteach other very tightly so as to make a rigid casing that will stand thepressure of driving the same into the well to be eased, which well mayin i some instances be of great depth, as 2000 feet, more or less.

An object of the invention is to provide superior means for forciblytelescoping the joints together and holding them while they "1 are beingriveted whereby the work will be .done with maximum rapidity, and jointsthat fit each other most tightly may be easily and evenly put together,thus making a strong, straight, rigid pipe. In the proc- T ess ofentering the joints, one end into another it is necessary for theworkman to have direct access to the pipe section on top, bottomand bothsides in order to effect the work in the most rapid and satisfactory "Imanner.

An objectof this invention is to construct a machine adapted totelescope the joints and in a manner to hold them, that will give freeaccess of the operator of the joints 1' for the purpose of entering oneend of one joint into the end of another and for the purpose of rivetingthe joints together.

The accompanying drawings illustrate the invention.

.Figure'l' is a fragmental side elevation of solid lines in positionready for ramming a pipe-section to add another pipe-joint thereto, saidpipe-joint being shown on the stake and against the abutment at the leftof the pipe-section. Dotted lines at the left of the view indicate aposition of the movable stake and its carriage before said joint wasplaced on the stake. Dotted lines at the right side of the View indicatethe position of the ram-piston after the ramming has been effected. Fig.2 is an elevation looking toward the left from line w Fig. 1. Fig. 3 isan elevation looking to the left from the arrow 3 in Fig. 1. Parts arebroken to show the screw that raises and lowers the ram. The parts shownin Fig. 1

2 are omitted from this view. Fig. 4 is a plan of the ram and its framelooking in the direction of the arrow 4 in Fig. 1. A portion of thecylinder is broken away to show the piston. carriage in position on thetrack, parts being broken to contract the view and expose parts thatwould otherwise be hidden. Fig. 0 is an enlarged detail on line 00,Figs. 2 and Fig. 5 is a plan of the stake- 1 5, showing the device forlocking the carriage against the thrust of the ram.

1 is a head mounted on a piston-rod 2 that is connected with a piston 3which is operated by fluid pressure in a cylinder 4 to move the headhorizontally. The parts 1, 2, 3, 4

constitute the ram. The same is adjustably mounted by means of a runner5 whichis fixed to the rear of the cylinder and is movable in a verticalway 6 that is supported by a frame 7 on which is mounted a nut 8 inwhich is a screw 9 controlled by a handwheel 10 and operating a block 11that is fastened by bolts 12 to the cylinder 1 for raising and loweringthe cylinder relative to the frame to bring the head centrally into linefor ramming pipes of different diameters.

The head 1 may be of cast iron having ribs 13 at the back to give itrigidity and may be faced with a plate 14 of sheet-steel, boileriron, orother rigid material to engage a pipe-joint that is to form a portion ofthe well-casing section which is formed of alternate inner and outerjoints, as at 15 and 16, teleseoped together.

one or more racks 18 the teeth of which face in one direction along thetrack.

19 is a riveting stake fixed to a frame 20 and projecting therefromtoward the ram- I ming head 1. Said frame 20 is provided with anabutment 21 that faces toward the ram to hold the pipe-joint 15 or 16,as the case may be, as it receives the thrust of a pipe-joint 16 or 15,as the case may be, which is to be telescoped therewith.

The frames 7 and 20 are relatively movable, and except for convenienceof operation or construction it is immaterial whether it is the holdingframe 20 or the ram-frame 7 that moves. is made stationary at one end ofthe track 17, and the holding frame 20 is movable Preferably, theram-frame 7 along the track, being provided with wheels 22 to run on topof rails 23 of the track.

In the form shown in the drawings, the ramframe 7 is fixed to the track17 and the holdthat run on internal flanges 25 of said track.

The track may be formed of two I-beams. 26 1 held together by bolts 27spaced apart by:

spacers 28.

The axle 29 of the thrust-resisting wheels f 24 is carried by hangers 30which consist of 1 plates through which the axles 31 of the supportingwheels 22 extend; said hangers 30 being perforated to receive the axles29 and 31, the latter of which is connected with the frame 20 by boxes32 which are secured by bolts 33 to the channel-iron hangers 34 to whichthe hangers 30 are rigidly fixed by rivets.

The stake-carriage composed of the frame 20, and the axles, wheels, andhangers just seated; the purpose being to resist the thrust of thestake-carriage when the ramming is being effected. engage the teeth 40of the racks except when The pawl 35 is adapted to held out ofengagement therewith by means under the control of the operator.

' means shown for this purpose consist of the hand,-l.ever 41 pivoted at42 to the stakeframe and connected by connecting-rod 43 with one arm 44of a crank-lever, the shaft 45 of which is journaled in boxes 46 on theThe stake-frame underneath the stake, the other l arm 47 of saidcrank-lever being connected by connecting-rod 48 with a bar 49 of thepawl that is fastened by bolts 50 to the sleeves 36 of the pawl so thatwhen the lever 41 is depressed the pawl 35 may be lifted above the teeth40 of the racks.

The holding carriage may be moved along the track by any suitable means.For this purpose a sprocket-wheel 51 is fixed to the rear axle 31 of theholding carriage and is connected by a sprocket-chain 52 with asprocket-wheel 53 that is fixed on sprocketshaft '54 that is journaledin the frame 20 and is provided with a crank 55 by which it may beturned to rotate the carriage-wheels 22 in one or the other direct-ionfor increasing or decreasing the space between the abutment and the ram.

The stake 19 is rigidly mounted in sockets 56-, 57, carried by the frame20 and is held in place by set-screws 58. Said stake projects from theframe 20 toward the ramhead 1 a distance something greater than thelength of one of the pipe-j oints which go to make up the pipe-section.Said stake is provided with a vertical perforation 59 for burs to gothrough when the stake is used for punching holes in the pipe-joints tobe connected.

60 is a goose-neck provided at its free end with the usual perforation61 to guide the punch for punching holes in the pipe-joints.

62 is a steel anvil seated in a seat 63 to i the stake for driving therivets that are to unite the pipe-joints.

The stake and goose-neck just described are common in the art.

The impelling fluid, whether water, oil, steam, or air, may becontrolled by a valve 64 operated by a shifting rod 65 which extendsalong the track within reach of the workmen, and may be suspended bycords 66 hung from the ceiling or from an elevated beam 67; said rodbeing connected by a link 68 with the valve-arm 69 so that as the rod isswung in one or the other direction it will move said valve-arm and turnthe valve to direct the fluid from the inlet or supplypipe 70 to one orthe other side of the piston 3 through one or the other of thefeed-pipes 71, 72; the exhaust passing out through the other feed-pipe72 or 71 as the case maybe, and through the valve 64 which is a fourwayvalve, to the outlet 73.

Trolleys 74 running on a track 75 and supporting sheaves 76 that carryloops 77 are provided to support the pipe-joints in position to berammed. The connection '78 between said sheaves and trolleys areadjustable by means of turnbuckles 79 so that the height to which thepipe-section will be held may be regulated.

in practical operation two pipe-joints, as 15 and 16, will be started totelescope together and will then be placed upon the stake 19, and thestake-carriage will "be brought sufficiently close to the head 1 whenthe same is retracted as in the position-shown in solid lines in Fig. 1,to allow the head when operated by its piston to drive the jointsagainst the abutment 21, and thereupon to ram the one joint half-wayinto the other; said joints being of equal length. In the operation oframming, the pawl 35 will be allowed to rest in the notches of the rackso that when the ramming occurs the holding-carriage will be heldrigidly on the track by the pawl and the thrust-wheels. After theram-head is retracted the loops 77 will be brought around the sectionjust formed, and the two pipe-joints will be swung in the loops freefrom the stake, and the lever 41 will then be pushed down to lift thepawl 35; whereupon the operator may turn the crank 55, thus to retractthe stake-carriage until another pipe-joint may be slipped onto or intothe end of the pipesection that is next the abutment. Then the carriagewill be run forward as before until the stake has fully entered thepipesection and the abutment is in position to hold the added joint forthe ramming action, whereupon the operation of ramming will be repeated.

It is usually desired to rivet the pipejoints together after they havebeen rammed. To do this each joint will be punched and riveted in theusual way while it is on the stake after having been rammed.

The stake is set on the carriage at such height as to accommodate thelargest diameters of pipe intended to be rammed, and in order to bringthe ramming head 1 to the appropriate height, the adjusting handwheel 10may be turned in either direction as required to bring the center of thehead into line 'with the axis of the pipe to be rammed. In order toallow this to be done readily the pipes 71 and 72 have flexibleconnections 81 and 82.

The lower ends of the hangers 30 may be held apart by a spacer 83 on theaxle 29, and cotter-pins 84 may be passed through such axle outside thewheels 24 to hold the parts in place.

Particular attention is directed to the construction whereby noobstructions are in the way of the workman relative to the joints, thepipe-section or to the stake, so that he is given perfect freedom inhandling the joints and section and the same are held by the stake readyfor the riveting operation immediately after the ramming process hasbeen performed, and all separation of the joints may be prevented bydriving a number of rivets while the joints are held by the ram.

I claim 1. A track provided with rails having flanges, a carriageprovided with wheels running on said track and provided with wheelsrunning under the flanges of said track, said carriage also beingprovided with an abutment, a rack extending along the track, a pawl onsaid carriage to engage said rack, and a ram to telescope joints of pipewhenheld by said abutment.

2. In a well casing machine, a track formed of two I-beams spaced apart,two frames, one of which is movable along the track toward and from theother, wheels for the movable frame to run on flanges of the I-beamswheels for the movable frame to run under flanges of the I-beams, a rackin fixed relation to the track, a pawl on the movable frame to engagethe rack, a ram on one of said frames, an abutment on the other frame,and means to operate the ram.

3. A pipe machine comprising a base; a frame mounted on the base andprovided with an abutment and with a pipe section supporting stake onthe same side of the frame; a second frame mounted on the base; saidframes extending up from the base and being in movable relation to eachother; a cylinder mounted on the second frame; a piston in the cylinder;the cylinder on the second f ame being opposed to the free end of the sake; a piston in the cylinder and a ram on the plston movable betweenthe frames toward and from the stake and abutment; the space above thebase and between the frames being open and unobstructed; means to supplyfluid to the cylinder to operate the piston, and means to temporarilyhold the frames in stationary relation to each other.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 3d clay of March, 1909.
